Python; get last answer

Posted on October 14, 2008

This my Answer to the stackoverflow question: Python; get last answer:

Just for the record, ipython takes this one step further and you can access every result with _ and its numeric value

In [1]: 10
Out[1]: 10

In [2]: 32
Out[2]: 32

In [3]: _
Out[3]: 32

In [4]: _1
Out[4]: 10

In [5]: _2
Out[5]: 32

In [6]: _1 + _2
Out[6]: 42

In [7]: _6
Out[7]: 42

And it is possible to edit ranges of lines with the %ed macro too:

In [1]: def foo():
   ...:     print "bar"
   ...:     
   ...:     

In [2]: foo()
bar

In [3]: %ed 1-2
